HARVEY B. LINDSAY, OF OAKLAND, CALIFORNIA.

REFRIGERATOR.

Application filed April 24, 1923. Serial No. 634,273.

To all whom it may concern:

Be it known that I, HARVEY B. LINDSAY, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

My invention is an improved refrigerator or cabinet particularly applicable for storing cans of ice cream and similar articles.

The object of my invention is to provide a refrigerator, in which the cream container is kept absolutely drythat is the brine or ice and salt never come in contact with the can.

Another object is to provide a refrigerator in which the brine tank is positioned above the bottom of the chamber-for containing the ice cream, thus enabling it to be readily drained, and yielding satisfactory refrigerating eflort to the last pound of ice and salt, which is not the case where the resultant brine forms at the bottom level of the refrigerator or cabinet.

A further object is to provide a refrigerator which is highly eflicient in operation. I

In the annexed drawing in which my invention is illustrated, I have shown the preferred form, but it may be embodied in other forms, and in this application I wish to cover my invention in whatever form it may be embodied.

Figure 1 is a plan view of my refrigerator.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Referring more particularly to the drawing, my refrigerator consists of a housing 1, which is preferably formed of wood, and of any desired shape. A tank 2 is mounted in the upper part of the housing, which tank is adapted to retain the cooling brine. An insulating material 3 is placed in the housing 1 below and at the sides of the tank 2, as shown.

One or more water-tight can receptacles 4 are positioned in the housing 1 as follows: The receptacles 4 project through the bottom of the tank 2 into the insulating material 3, and the juncture 5 between said tank and receptacle is hermetically sealed. The upper portions of the receptacles pro- .ject into the tank and are surrounded therein only by the cooling brine, the joints 5 preventing the brine from flowing into the insulating material 3.

The cans containing the cream are placed in the receptacles 4, in which they are kept cold and dry. The present method of placing the cans directly in the brine causes them to deteriorate very rapidly due to the chemical action of the brine thereon. In spite of the very desirable and sanitary feature of protecting the cans from contact with the brine, as low a temperature is maintained in my refrigerator as in the present box, and the cans will not deteriorate because of their separation from the brine.

Having described my invention I claim:

' 1. A refrigerator comprising a housing, a tank mounted in the upper part of said housing, insulating material in said housing around said tank, and a receptacle positioned partially within said tank and within said insulating material.

2. A refrigerator comprising ahousing, a tank in said housing adapted to receive the cooling mixture, an insulating material below the tank and a receptacle adapted to pass through the bottom of said tank to ex tend partially into the insulating material and a hermet-ical seal at the juncture of said receptacle and said tank.

3. A refrigerator comprisin a housing, a tank in the upper portion thereof, adapted to contain a cooling mixture, an insulating material below the tank, a water-tight receptacle within said tank and protruding through the bottom thereof and hermetically sealed where it passes through said bottom.

4. A refrigerator comprising a housing, a tank in the upper portion thereof, adapted to contain a cooling mixture, a water-tight receptacle Within said tank and protruding through the bottom thereof and hermetically sealed where it passes through said bottom, and insulating material in the space between said housing and said tank and ing a Water-tight receptacle passing through around the protruding portion of said rethe bottom of said tank and hermetically 1 ceptaole. sealed to the tank bottom at point of pene- 5.
